Lin the form of the invention shown in Fige. k2, and 55 such subsiiaiy sii c is of me seme iengtii as the mein slipu but helft the Width of'iie main sip, Assuanihet the oiange desired is e change of 52 Canal sti'eet, Boston, Erifge si'eet, New Yeaj'; the inf address om Mess. to 1208 Witheu, changing any oshei of c be a temporary address, the original ad.

dress ma be aOain restored to view b i simply withdrawing the subsidiary slip c, which may be stored in the sheath behind inain slip o in case it should be re uired for use a ain i n J as ireqnently happens, as in cases, for example, where lists are required to show al.-

ternately a permanent and a summer address. y

Thus the indicator or index may be quickly and conveniently altered in respect to part of its inscriptions, or restored again to its original condition,- Without the necessity of copying or rewriting any part of the main slip, which would involve labor, and danger of mistakes, and without even removing the inai'n slip from the sheath.

In the modilication shown in Fig. 6, the sheath i and the main indicator slip Z) are the same as already described, excepting that the inscription on the slip a shows the naine on the left hand end oil the slip and the address on theright hand end, instead of on the upperand lower parts respectively, as in Fig. 3. ln such case, in order to change the inscription at one end of the main slip, as distinguished from the longitudinal inargin as before, l provide the subsidiary slip c', which bears the new or altered inscription, and slides into the sheath, covering that portion of the main slip which is to be changed, and leaving other parts of the main slip exposed. The slip c is-shown in Fig. 6' as partially withdrawn from the sheath.

It will thus be seen that in either form ci' the invention the subsidiary indicator strip is of smaller area than the main strip so `as to partially cover the face of the main strip leaving part thereof exposed, and that one of thedimensionsoig the face ot the subsi diary strip,the longitudinal dimension 0i' strip c and `the transverse dimension of strip c,-is substantially the same as the corresponding interior dimension of the sheath;

ln order to facilitate the removal of the slips from the sheath, I have provided in one or both ends of the sheath a notch (i3. By' inserting a pointed implement, or a. finger nail of the user, into thisA notch the slips nia-y be pushed far enough out of the sheath to en- Aable the projecting end to be seized by the ngers and the slips Withdrawn. Cr, the slips may be seized within the notch and withdrawn. Said notches may also be used, in the form of the device shown in Fig. 5, to admit a pointed implement to straighten or adjust the subsidiary slip laterally, after it has been inserted in the sheath, in case it should. not lie straight, or should Wholly or partiallyeover the Wren g part of main slip o; and further, by reason of said notches the subsidiary slip may be Withdrawn, it desired, by a pointed implement Without disturbing the main slip.

I claim:

l. In combination, a transparent sheath having a closed front face adapted to receive and hold removable indicator slips,

main removable indicator slip adapted to slide in and out of said sheath, and being of substantially the saine length and width as the length and width of the interior of said sheath, and a subsidiary indicator slip nai'- rower lthan the main slip, adapted to slide in and outo said sheath between the main slip and said closed front face ot the sheath and to cover one longitudinal margin of said main slip leaving the other mar-gin thereof exposed. n

2. In combination, a sheath of transparent sheet Celluloid having a closed front face and inturned guide flanges, said sheath be ing open at its ends to permit indicator strips to be inserted and removed through the ends, a main removable indicator strip adapted to slide in and out ot said sheath and being ot' substantially they saine length 4this 23rd day of March 1912.
